BOX-SANDING MACHINE.

SPECIFICATION forming part of Letters Patent No. 709,033, datedSeptember 16, 1902.

Application filed January 9, 1900. $eri'al No. 882. (No model.)

To (all whom, it may concern:

Be it known that we, CHARLES HENRY PALMER and JOHN W. DENMEAD, of Akron,in the county of Summit, and in the State of Ohio, have invented certainnew and useful Improvements in Box-Sanding Machines; and

. We do hereby declare that the following isa Fig. 2 is a top plan Viewthereof.

The object of our invention is to provide a machine for forming thescratch-surfaces of match-boxes which will be capable of doingsatisfactory work and doing it very rapidly and to this end saidinvention consists in the sanding machine substantially as hereinafterspecified.

Our machine has been designed to apply sand to the exterior surface ofmatch-boxes of the class consisting of a tray or receptacle part and acover part in the form of a flatsided tube, the cover part beingcommonly called the shuck or slide, and the sand being applied to it.

Briefly set forth, the machine comprises a source of supply of shucks orslides to be sanded in the form of a trough or guide, arapidly-reciprocating bar upon whose end the slides one at a time aretaken, and a sanding mechanism comprising a glue-applying device pastwhich the slides are moved by the bar, and a sanding device to and pastwhich the slides are moved after receiving the glue.

In the embodiment of the invention shown in the drawings the variousparts of the machine are mounted upon a table or bed A,supported bysuitable legs a and a. Above the table A upon proper supports is ahorizontal trough or guide 13, that is open from end to end and at thetop,and close to the bottom of which for a portion of its length rnusaband I), that passes over a pulley b at one end of the trough andanother, b between the ends of the trough, power being applied to thelatter pulley to drive said band. At one side of and parallel with saidtrough is a horizontal bar C, that'is attached at one end to a slidinghead a, mounted on horizontal guides D and D, bolted to standards E andE on the table A. The head cis reciprocated by means of a crank-disk F,to the Wrist-pin of which it is connected by a pitman G, said diskbe--ing on a shaft H, having a driving wheel or pulleyI. The free end of thebar C travels in a path that extends from a point a short distance inrear of the adjacent end of the trough B to a point some distance beyondsuch end. The shape of the free end of the bar C in cross-section isrectangular, and its size is such that it will fit within the slide tobe sanded. Each slide as it emerges from the trough B is in the path ofa carrier that reciprocates at a right angle to the trough and moves theslide into the path of the bar O, whose end passes into the slide as thebar moves forward, its end being beveled to enable it to readily enterthe slide. Said carrier consists of a horizontal bar K, movable in suitable supports and having on its upper side a vertical projection L,which engages the side of the slide as it comes from the trough B. A camM, engaging a stud It on the bottom of the bar K, and a spring N,connected at one end to the latter and at the other to a relativelyfixed point and acting in opposition to the cam, produce thereciprocation of the bar K. The cam is on a shaft 0, having asprocket-wheel P, by which it is connected by a sprocket-chain Q to asprocket-wheel Son theshaft II. To prevent the slide being moved too faron emerging from the trough B, a stop It on the bar K comes opposite theopen end of the trough, While to prevent the slide being moved beyond aposition in alinement with the bar C a stop J is used. Exit of slidesfrom the trough B while the slide-carrier is moving across its end isprevented by means of a second vertical projection L on theslide-carrier, which closes such end of the trough during mechanism theslide is carried by the further movement of the bar into a trough.

ing the movement of the carrier. Onone side of the bar C are shouldersor lugs c and c, which engage the inner end of the slide when the barenters the latter, and the slide is thereby carried along with the bar.In its movement with the bar C the slide is carried over a glue-applyingmechanism U, of usual construction, comprising a pan or vat and a wheelthat takes glue from the vat and applies it to the slide,and from saidglue-applyor guide V, having top and sides, but no bottom. In itsdescribed travel with the bar 0 the slide passes beneath a spring-plateW, fastened at one end to the top of said trough V, and any deformationof the slide which may exist at such time is removed by the pressure ofthe spring. Having placed the slide in the trough V, the return movementof the bar 0 takes place, and for removing the slide from it there is astripping device in the form of a spring X, attached to and projectingfrom the trough, with its free end hooked to catch over the rear end ofthe slide and hold the latter from rearward movement with the bar 0. Theslides are moved through the trough V by those in the rear engaging andpushing the ones in advance, and in such movement they pass over asanding device Y, of usual construction, comprising a rapidly-revolvingwheel that takes sand from a receptacle and throws it against the gluepreviouslyapplied to the under side of the slides. Theinteriordimensions of the trough V are such that the natural outward spring ofthe sides of the slides presses with sufiicient friction on thetrough-walls to prevent the slides dropping out of the trough. Thetrough V ends a short distance beyond the point where 'the sand isapplied to the slides, and the latter passing from the trough fall fromthe machine. The glue-wheel shaft Z has a band wheel or pulley A for adriving-belt, and from said shaft a train of gears transmits power tothe sand-wheel, and also on said shaftZ is a pulley B, that is connectedby a belt 0 with a pulley D upon the shaft carrying the band-wheel bpower being thus transmitted to the latter to drive the slidefeedingband I).

The operation of the machine is as follows: Slides are placed by hand inthat portion of the trough B through which the band I) runs, and restingon the latter they are carried end to end through the trough, those inthat portion not traversed by the band being pushed onward by those thatare. The end one of the row of slides emerging from the trough is by thestop is arrested in the path of the projection L of the carrier-bar Kand by the movement of the latter is carried into the path of the bar 0,which is rapidly reciprocated. Stopped in the path of said bar by thelug or flange T, the bar in its forward travel enters the slide, itsshoulders c and c engaging the adjacent end thereof, and the slide isthen carried over the glue-wheel and beneath the,

spring W and then into the trough V, being stripped from the bar 0 asthe latter moves rearward. Pressed onward through the trough V by thesucceeding slides, the one in advance is carried over the sanding-wheeland finally makes its exit from thetrough V perfectly sanded and inperfect form. As the construction of the machine permits theslide-carrying bar 0 to be reciprocated at high speed, the rapidity withwhich the machine can sand slides is practically limited only by therate at which slides are fed into the receiving-trough B.

Having thus described our invention, what we claim is-- 1. In asanding-machine, the combination of sanding mechanism, a reciprocatingbar by which box parts are conveyed to the latter, and means for feedingbox parts in a path crosswise of said bar, in position for the end ofthe latter to enter therein, substantially as and for the purposedescribed.
